Sequence does not exists.

Posted on 2013-11-13
Last Modified: 2013-11-19
I have a sequence in remote DB. I am able to access the sequence (get nextval)
from a normal query in sql window, but I am not able to access it inside a procedure.

I am using the same username for querying and for procedure.

For procedure, I am getting sequence does not exists.

What could be the reason?

Does the procedure exist in the same schema? If not, you can access your sequence like this:

1. make sure the relevant DB link is working fine
2. ensure you have been granted with the privileges to use this sequence

Hi all
I am sorry, sequence is in the same DB only.

But I was having the public synonym. using that I can query in sql window, but not able to use it inside procedure.

What could be the reason.?

Is the synonym granted to you? How about to directly refer to the sequence name instead?

you can check what sequences you have access to with user_sequences
in your schema
select * from user_sequences@remote_db;

and in the other schemas:
select * from all_sequences@remote_db;

if the grant to the sequence was given via a role to the user
then it will be accessible from a normal query but not from within pl/sql

It may be that you have permissions on the sequence through a role, which is not carried over in a procedure. Try adding the AUTHID CURRENT_USER clause in your procedure declaration -
create or replace procedure myproc(params in datatypes)
authid current_user as

In your trouble-shooting, may I strongly recommend that you debug first using SQL*Plus rather than PL/SQL.  That's the best way I know of to ensure whether or not your statement is clean.

My guess is the correct solution was the first one selected.

It is likely a GRANT issue.  The GRANT needs to be given directly and not through a ROLE.
